' '1 1-Claims. (o1.1s4 1o4)' The present invention is related generallyto" perforating machines, but more particularly to a.

novel and improved arrangement for supporting, locking and securing thepunches thereof in opertive or in inoperative positions.

One of the objects of the present invention is to provide a novel andimproved construction of a quick, adjustable support for the punches ofa perforating machine, in which a plurality of punches are supportedtherein so that the same may be adjusted to and locked in their normaloperative positions or locked in their inoperative positions, so thatdifferent spacing between the perforations may be secured. V

These and other'objects are accomplishedby providing a'construction. andan arrangement of the various parts in the manner hereinafter describedand particularly pointed outin the ap-.

pended claims. I

Referring to the drawing: Fig. 1 is a frontelevational view offragmentary portion of a perforating machine showing my inventionembodied therein; a

Fig. 2 is .a cross-sectional view taken on the ;line 22 in Fig. 1; aFig. 3 is a perspective view of the punch locking slug; r a

Fig. 4 is a sideview of one of. the punches and Fig. 5 is a crosssectional viewtaken onvthe line 5-5 in Fig. 1.

In illustrating one embodiment of myinven tion, I have shown the samein'connection with a perforating machine of the construction dc scribedand illustrated in myU. S. Letters Patent No. 1,845,714,.issued February16, 1931, on a Perforating machine. This perforating machine,

only a fragmentary portion of the same. being shown in the drawing,comprises a reciprocating head generally indicated by. the reference.character 10 and a stationary bed generally indicated by the referencecharacter 11.

(not shown) which may be of;any well known construction. Extendinglongitudinally of the front face of the reciprocating head 10 isarecured bymeans of bolts 13, a punchsupporting block 14. The punchsupporting block 14 is provided with a plurality of vertically extendingholes or bores 15, which are arranged in spaced apart relation. Mountedin these-bores 15 are punches lfi, 17,-18, 19, 20 and 21. The punches16, 1'7 and 18 are identical in -size; but with relatively smaller'punchheads, as shown at 22;"than the punches19, 20 and '21, as shown at 23.-This The opposite ends of the head 10 are suitably supported in guidesarrangement permits the. punches 16 and 1'7 to be'used in a pair, or thepuncheslG and 18 to be used in a pair, so that differentspacing of the 9same size perforations may be had. On the other hand, if a largerdiameter of perforation is required, the punches 19 and 20 may be usedin a pair, or the. punches 19 and 21 may be used in a. pair to secure adifferent spacing 'oftthe perforations. Arranged contiguous with thebores 15 of the punch block 14 are recesses 24 which are adapted toreceive when the punches are in the normal operative position, pins 25which are secured adjacent the upper ends of each of the punches 16,1'7, 18, 19, 20 and 21. .Whenj the operator desires to withdraw certainpunches from their normal positions, that is, their normal operatingpositions,,the punches are raised so that the pins 25 are withdrawn fromthe recesses 24 and seated in semi-circular recesses 26 located on theupper and outer edge of the punch block 14. Each of the punches isprovided on their front face with a rectangular. recess as shown at-27.The recess 27islocated below the Y vided above the recess 27 andfat.right angles with respect to the recess" 27,-.With a second rectangularrecess generally indicatedby the ref-' erence character 28., Extendinglongitudinallyv 5 a of the punch block 14 ata point slightly below' theupper surface thereof, is a rectangular socket 29 which communicateswith eachof the bores 15 in the block 14. Mounted in therecess 29. is

a removable punch locking slug or, bar 30. This, 9'0

locking slug or bar-3O is adapted -to engage'the recesses 28 .of each ofthe punches when'they are in their operative positions or the positionscccupiedbythe punches 19 and 20, andisadapted to engage the recesses" 27when the punches arev 95' in their inoperative position'or the positionsoccupied by the punches 16, 1'7, 18 and 21, The

slug or bar 30 is secured against displacement 'on the punchblock 14, bymeans of cap, screws 51,

which are mounted in threaded engagement with-1o0 the block '14 sdthatthe headslth'ereofengage' the outer surface of the bar-or slug 30 as:clearly shown in Fig. 1 of the drawing. The bar 30 is provided with anotch as shown; at 32 so the same may be removed by hand or wane" toolafter the I65 cap screws 31 are loosened. s V Formed on the forward sideof 1 and overhanging the upper surface of the bed 11,-is an"L-shapedrecess generally indicated by the reference-character-33KSecuredin the recess 33 by means oil- 0 PATE HCT in, their operativeposition for perforating the material or paper as it is passedthereunder. Each of these apertures, 36, 37, 38, 39, 4 0 and 41communicates with enlarged apertures 42' extending vertically thru thebeds 11 and which, in turn, communicate with an enlarged recess,indicated generally by the reference character 43 in the lower portionof the bed 11 so as toallow for the escape of the waste material.

The operation of my improved perforating device is as follows: Ihepunches 19 and as shown in Fig. 1 of the drawingare in their operativeposition, while the punches 16, l7, l8 and 21 are in their elevated orinoperative position. Let us assume that the operator desires toposition the punches 16 and 18 in their operative positions and raisethe punches 19 and 20 to their elevated or inoperative positions. Toaccomplish this the cap screws 31 are loosened and the locking bar 30removed. After this has been done, the punches l9 and 20 may be raisedby gripping the upper end or head of the punch and raising the samevertically, so as to disengage them from the sockets 24 in the block 14,then by rotating the punches a quarter of a turn, the pins 25 may beseated in the recesses I 26. When punches i9 and 20 are thus positioned,recesses 27 will register with the longitudinal recess 29, where theymay be engaged by the locking bar 30 when the same is inserted. Then tolower the punches 16 and 18 to their operative positions, they areslightly raised so the pins 25 become disengaged from the semicircularrecesses 25 and are turned a quarter of a turn in a cross wise directionuntilthese pins 25 register with the sockets 24 in the upper end of theblock. 14 after which they may be dropped in the socket so that the.rectangular recesses 28 in each of the punches l6 and 18 are'inregistering alignment with the longitudinal recesses 29 in the block 14.After this has been accomplished the bar 30 may be inserted andsecuredinplace by the clamp screw 31, thereby positioning the punches 16 and 18in. their lowered or operative positions, while the remaining punchesare raised and locked in their inoperative positions so that 7 upon areciprocation of the head 10 in cooperation with the die 35, the paperpassing therei through will be perforated by the two punches '16 and 18.In a similar manner any set of punches may be adjusted and locked intheir operative position on the head while the remaining punches mayberaised-and locked in their inoperative p0- sitions on the head.

While in the above specificationI have descrlbed chine, of areciprocating head therefor, punch oneiembodiment which myinvention mayassume in practice, itwill, of course, be understood the same is capableof modification and that modification may be employed without departingfrom secured to said head, a plurality of punches car certain other ofsaid punches in inoperative positions on said block.
